This application is a continuation of U.S. patent application Ser. No.17/182,143, filed Feb. 22, 2021, now U.S. Pat. No. 11,350,144, which isa continuation of U.S. patent application Ser. No. 16/216,655, filedDec. 11, 2018, now U.S. Pat. No. 10,931,984, both of which are hereinincorporated by reference in their entirety.

The present disclosure relates generally to digital data distribution,and relates more particularly to methods, computer-readable media, anddevices for consolidating multiple data streams that are streaming thesame multimedia content to different devices.

BACKGROUND

Streaming media includes various types of multimedia content (e.g.,television programs, video clips, music, podcasts, books,advertisements, and the like) that are delivered over a network ascontinuous streams of data (e.g., packets). For instance, a userendpoint device may establish a connection, via a telecommunicationsservice provider network, to a server on which a file containing a videois stored. The file may be transmitted over the network to the userendpoint device as a stream of packets, where each packet contains aportion of the video. The user endpoint device may store these packetstemporarily in a buffer so that the contents of the packets can bedecoded and played back. As newer packets are received into the buffer,older packets containing content that has already been decoded andplayed back may be discarded.

SUMMARY

The present disclosure provides methods, computer-readable media, anddevices for consolidating multiple data streams that are streaming thesame multimedia content to different devices. In one example, a methodincludes monitoring a delivery of an item of multimedia content to afirst user endpoint device in a first stream of data, monitoring adelivery of the item of multimedia content to a second user endpointdevice in a second stream of data, consolidating the stream of data andthe second stream of data into a third stream of data, sending an firstinstruction to a source of the first stream of data and a source of thesecond stream of data to cease delivering the first stream of data andthe second stream of data, and sending a second instruction to thesource of the first stream of data and the source of the second streamto begin delivering the third stream of data to the first user endpointdevice and the second user endpoint device.

In another example, a device includes a processor and a non-transitorycomputer-readable medium storing instructions which, when executed bythe processor, cause the processor to perform operations. The operationsinclude monitoring a delivery of an item of multimedia content to afirst user endpoint device in a first stream of data, monitoring adelivery of the item of multimedia content to a second user endpointdevice in a second stream of data, consolidating the stream of data andthe second stream of data into a third stream of data, sending an firstinstruction to a source of the first stream of data and a source of thesecond stream of data to cease delivering the first stream of data andthe second stream of data, and sending a second instruction to thesource of the first stream of data and the source of the second streamto begin delivering the third stream of data to the first user endpointdevice and the second user endpoint device.

In another example, a computer-readable medium stores instructionswhich, when executed by a processor of a user endpoint device, cause theprocessor to perform operations. The operations include monitoring adelivery of an item of multimedia content to a first user endpointdevice in a first stream of data, monitoring a delivery of the item ofmultimedia content to a second user endpoint device in a second streamof data, consolidating the stream of data and the second stream of datainto a third stream of data, sending an first instruction to a source ofthe first stream of data and a source of the second stream of data tocease delivering the first stream of data and the second stream of data,and sending a second instruction to the source of the first stream ofdata and the source of the second stream to begin delivering the thirdstream of data to the first user endpoint device and the second userendpoint device.

DETAILED DESCRIPTION

In one example, the present disclosure provides methods,computer-readable media, and devices for consolidating multiple datastreams that are streaming the same multimedia content to differentdevices. As discussed above, streaming media involves deliveringmultimedia content over a network as a continuous stream of data (e.g.,packets). As the number of services offering streaming media and thesophistication of the media itself continue to increase, so too does theamount of network bandwidth consumed by the streaming media. Forinstance, some recent studies have estimated that video streaming mayaccount for almost half of all Internet traffic and more than a third ofall hypertext transfer protocol (HTTP) traffic.

Examples of the present disclosure reduce the amount of bandwidthconsumed by streaming media by consolidating or merging multiple datastreams that are streaming the same multimedia content to differentdevices. In some examples, consolidation of the multiple streams mayinvolve modifying the speed at which at least one of the streams isdelivered.

For instance, a first user and a second user living on the same block asthe first user may be streaming the same television show through a videoon demand (VOD) service, but the first user may have started playing thetelevision show back fifteen seconds before the second user started.Some VOD services might deliver the television show to a first userendpoint device of the first user as a first unicast stream and alsodeliver the television show to a second user endpoint device of thesecond user as a second unicast stream. This, in effect, doubles theamount of bandwidth consumed in delivering the television show to boththe first and second users.

However, examples of the present disclosure may slow down the speed atwhich the television show is delivered to the first user endpoint devicewhile also speeding up the speed at which the television show isdelivered to the second user endpoint device, until the television showis synchronized on the first user endpoint device and second userendpoint device (e.g., the first user endpoint device and the seconduser endpoint device are playing the same frame(s) of the televisionshow at the same time). At this point, the television show may bedelivered as a single broadcast stream to both the first user endpointdevice and the second user endpoint device, thereby reducing the amountof bandwidth consumed in delivering the television show to both devices.

Although examples of the present disclosure may be discussed within theillustrative context of viewable multimedia content (e.g., televisionprograms, movies, advertisements, and the like), it will be appreciatedthat the examples described herein could also be applied to other typesof streaming multimedia. For instance, examples of the presentdisclosure could be implemented to reduce the bandwidth consumed bystreaming audio multimedia content (e.g., music, podcasts, audio books,and the like), printed multimedia content (e.g., books, magazines,newspapers, and the like), and other types of multimedia content.

To better understand the present disclosure, FIG. 1 illustrates anexample network 100, related to the present disclosure. The network 100may comprise part of a telecommunications service provider network. Asshown in FIG. 1, the network 100 connects mobile devices 157A, 157B,167A and 167B and home network devices such as home gateway 161, set-topboxes (STBs) 162A, and 162B, television (TV) 163A and TV 163B, homephone 164, router 165, personal computer (PC) 166, smart home or“Internet of Things” (IoT) device 116 (e.g., smart thermostat, smartlighting system, Internet radio intelligent personal assistant, etc.),and so forth, with one another and with various other devices via a corenetwork 110, a wireless access network 150 (e.g., a cellular network),an access network 120, other networks 140 and/or the Internet 145.Mobile devices 157A, 157B, 167A and 167B, and home network devices suchas home gateway 161, set-top boxes (STBs) 162A, and 162B, television(TV) 163A and TV 163B, home phone 164, router 165, personal computer(PC) 166, and smart home device 116, may also be referred to herein as“customer devices” or “user endpoint devices.” As discussed in furtherdetail below, the user endpoint devices may run applications throughwhich multimedia content can be streamed. These applications may alsocommunicate with a centralized controller to report data and receiveinstructions regarding the status of multimedia content being streamedon the user endpoint devices.

In one example, wireless access network 150 comprises a radio accessnetwork implementing such technologies as: global system for mobilecommunication (GSM), e.g., a base station subsystem (BSS), or IS-95, auniversal mobile telecommunications system (UMTS) network employingwideband code division multiple access (WCDMA), or a CDMA3000 network,among others. In other words, wireless access network 150 may comprisean access network in accordance with any “second generation” (2G),“third generation” (3G), “fourth generation” (4G), Long Term Evolution(LTE) or any other yet to be developed future wireless/cellular networktechnology including “fifth generation” (5G) and further generations.While the present disclosure is not limited to any particular type ofwireless access network, in the illustrative example, wireless accessnetwork 150 is shown as a UMTS terrestrial radio access network (UTRAN)subsystem. Thus, elements 152 and 153 may each comprise a Node B orevolved Node B (eNodeB).

In one example, each of mobile devices 157A, 157B, 167A, and 167B maycomprise any subscriber/customer endpoint device configured for wirelesscommunication such as a laptop computer, a Wi-Fi device, a PersonalDigital Assistant (PDA), a mobile phone, a smartphone, a portable gamingdevice, an email device, a computing tablet, a messaging device, aglobal positioning system (GPS), a satellite radio receiver or satellitetelevision receiver, and the like. In one example, any one or more ofmobile devices 157A, 157B, 167A, and 167B may have both cellular andnon-cellular access capabilities and may further have wiredcommunication and networking capabilities.

As illustrated in FIG. 1, network 100 includes a core network 110. Inone example, core network 110 may combine core network components of acellular network with components of a triple play service network; wheretriple play services include telephone services, Internet services andtelevision services to subscribers. For example, core network 110 mayfunctionally comprise a fixed mobile convergence (FMC) network, e.g., anIP Multimedia Subsystem (IMS) network. In addition, core network 110 mayfunctionally comprise a telephony network, e.g., an InternetProtocol/Multi-Protocol Label Switching (IP/MPLS) backbone networkutilizing Session Initiation Protocol (SIP) for circuit-switched andVoice over Internet Protocol (VoIP) telephony services. Core network 110may also further comprise a broadcast television network, e.g., atraditional cable provider network or an Internet Protocol Television(IPTV) network, as well as an Internet Service Provider (ISP) network.The network elements 111A-111D may serve as gateway servers or edgerouters to interconnect the core network 110 with other networks 140,Internet 145, wireless access network 150, access network 120, and soforth. As shown in FIG. 1, core network 110 may also include a pluralityof television (TV) servers 112, a plurality of content servers 113, aplurality of application servers 114, an advertising server (AS) 117, acontroller 115, and a buffer or buffers 180. For ease of illustration,various additional elements of core network 110 are omitted from FIG. 1.

With respect to television service provider functions, core network 110may include one or more television servers 112 for the delivery oftelevision content, e.g., a broadcast server, a cable head-end, and soforth. For example, core network 110 may comprise a video super huboffice, a video hub office and/or a service office/central office. Inthis regard, television servers 112 may interact with content servers113 and advertising server 117 to select which video programs, or othercontent and advertisements to provide to the home network 160 and toothers.

In one example, content servers 113 may store scheduled televisionbroadcast content for a number of television channels, video-on-demandprogramming, local programming content, and so forth. Content serversmay also store non-video content, such as podcasts, audio books,electronic books, music, and the like. Content providers may uploadvarious contents to the core network to be distributed to varioussubscribers. Alternatively, or in addition, content providers may streamvarious contents to the core network for distribution to varioussubscribers, e.g., for live content, such as news programming, sportingevents, and the like.

In one example, advertising server 117 stores a number of advertisementsthat can be selected for presentation to viewers, e.g., in the homenetwork 160, via the mobile devices 157A, 157B, 167A, and 167B, and atother downstream viewing locations. For example, advertisers may uploadvarious advertising content to the core network 110 to be distributed tovarious viewers.

In one example, one or more of the application servers 114 may host asocial media application, e.g., an Internet-based application via whichusers can create and share of information. For instance, the socialmedia application may comprise a personal and/or professional socialnetworking application, a blogging or microblogging application, animage or video sharing application, a web feed, or the like. The socialmedia application may maintain a profile for each user of the socialmedia application, which the user can update at any time. The socialmedia application may also allow the user to consume content uploaded byother users and to comment on, rate, or review the content uploaded bythe other users.

In one example, the television servers 112, content servers 113,application servers 114, and advertising server 117 may begeographically distributed in various locations. As discussed in furtherdetail below, this may allow multimedia content to be dynamically and/ortemporarily downloaded (e.g., under the direction of the controller 115)to servers whose location is relatively close to a location where theremay be a greater demand for the multimedia content.

The buffer 180 may store portions (e.g., chunks or other segments) ofitems of multimedia content that are currently being streamed from anyof the TV server(s) 112, content server(s) 113, application server(s)114, and ad server 117. In this way, the buffer(s) 180 may act as arelay that facilitates consolidation of data streams when two morenetwork users are streaming the same item of multimedia content.

In one example, the controller 115 comprises a server or computingdevice that has access to the content stored on the TV server(s) 112,content server(s) 113, application server(s) 114, and ad server 117. Thecontroller 115 may access content from any of these sources and deliverthe content to the user endpoint devices (e.g., mobile devices 157A,157B, 167A and 167B, and home network devices such as home gateway 161,set-top boxes (STBs) 162A, and 162B, television (TV) 163A and TV 163B,home phone 164, router 165, personal computer (PC) 166, and smart homedevice 116) as streams of data (e.g., packets). In one example, thecontroller 115 may collect data from the user endpoint devices, and,based on the collected data, modify the manner in which one or morestreams of data are delivered to the user endpoint devices. Forinstance, as discussed in further detail below, the controller 115 maymodify the speed with a stream of data is delivered to allow forconsolidation of the stream of data with at least one other stream ofdata.

In one example, any or all of the television servers 112, contentservers 113, application servers 114, controller 115, and advertisingserver 117 may comprise a computing system, such as computing system 300depicted in FIG. 3.

In one example, the access network 120 may comprise a Digital SubscriberLine (DSL) network, a broadband cable access network, a Local AreaNetwork (LAN), a cellular or wireless access network, a 3^(rd) partynetwork, and the like. For example, the operator of core network 110 mayprovide a cable television service, an IPTV service, or any other typeof television service to subscribers via access network 120. In thisregard, access network 120 may include a node 122, e.g., a mini-fibernode (MFN), a video-ready access device (VRAD) or the like. However, inanother example node 122 may be omitted, e.g., for fiber-to-the-premises(FTTP) installations. Access network 120 may also transmit and receivecommunications between home network 160 and core network 110 relating tovoice telephone calls, communications with web servers via the Internet145 and/or other networks 140, and so forth.

Alternatively, or in addition, the network 100 may provide televisionservices to home network 160 via satellite broadcast. For instance,ground station 130 may receive television content from televisionservers 112 for uplink transmission to satellite 135. Accordingly,satellite 135 may receive television content from ground station 130 andmay broadcast the television content to satellite receiver 139, e.g., asatellite link terrestrial antenna (including satellite dishes andantennas for downlink communications, or for both downlink and uplinkcommunications), as well as to satellite receivers of other subscriberswithin a coverage area of satellite 135. In one example, satellite 135may be controlled and/or operated by a same network service provider asthe core network 110. In another example, satellite 135 may becontrolled and/or operated by a different entity and may carrytelevision broadcast signals on behalf of the core network 110.

In one example, home network 160 may include a home gateway 161, whichreceives data/communications associated with different types of media,e.g., television, phone, and Internet, and separates thesecommunications for the appropriate devices. The data/communications maybe received via access network 120 and/or via satellite receiver 139,for instance. In one example, television data files are forwarded toset-top boxes (STBs)/digital video recorders (DVRs) 162A and 162B to bedecoded, recorded, and/or forwarded to television (TV) 163A and TV 163Bfor presentation. Similarly, telephone data is sent to and received fromhome phone 164; Internet communications are sent to and received fromrouter 165, which may be capable of both wired and/or wirelesscommunication. In turn, router 165 receives data from and sends data tothe appropriate devices, e.g., personal computer (PC) 166, mobiledevices 167A, and 167B, and so forth. In one example, router 165 mayfurther communicate with TV (broadly a display) 163A and/or 163B, e.g.,where one or both of the televisions is a smart TV. In one example,router 165 may comprise a wired Ethernet router and/or an Institute forElectrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi) router, andmay communicate with respective devices in home network 160 via wiredand/or wireless connections.

It should be noted that as used herein, the terms “configure” and“reconfigure” may refer to programming or loading a computing devicewith computer-readable/computer-executable instructions, code, and/orprograms, e.g., in a memory, which when executed by a processor of thecomputing device, may cause the computing device to perform variousfunctions. Such terms may also encompass providing variables, datavalues, tables, objects, or other data structures or the like which maycause a computer device executing computer-readable instructions, code,and/or programs to function differently depending upon the values of thevariables or other data structures that are provided. For example, oneor both of the STB/DVR 162A and STB/DVR 162B may host an operatingsystem for presenting a user interface via TVs 163A and 163B,respectively. In one example, the user interface may be controlled by auser via a remote control or other control devices which are capable ofproviding input signals to a STB/DVR. For example, mobile device 167Aand/or mobile device 167B may be equipped with an application to sendcontrol signals to STB/DVR 162A and/or STB/DVR 162B via an infraredtransmitter or transceiver, a transceiver for IEEE 802.11 basedcommunications (e.g., “Wi-Fi”), IEEE 802.15 based communications (e.g.,“Bluetooth”, “ZigBee”, etc.), and so forth, where STB/DVR 162A and/orSTB/DVR 162B are similarly equipped to receive such a signal. AlthoughSTB/DVR 162A and STB/DVR 162B are illustrated and described asintegrated devices with both STB and DVR functions, in other, further,and different examples, STB/DVR 162A and/or STB/DVR 162B may compriseseparate STB and DVR components.

Those skilled in the art will realize that the network 100 may beimplemented in a different form than that which is illustrated in FIG.1, or may be expanded by including additional endpoint devices, accessnetworks, network elements, application servers, etc. without alteringthe scope of the present disclosure. For example, core network 110 isnot limited to an IMS network. Wireless access network 150 is notlimited to a UMTS/UTRAN configuration. Similarly, the present disclosureis not limited to an IP/MPLS network for VoIP telephony services, or anyparticular type of broadcast television network for providing televisionservices, and so forth.

To further aid in understanding the present disclosure, FIG. 2illustrates a flowchart of an example method 200 for consolidatingmultiple data streams that are streaming the same multimedia content todifferent devices. In one example, the method 200 may be performed by aserver such as the controller 115 illustrated in FIG. 1 and/or thecomputing device 300 illustrated in FIG. 3. However, in other examples,the method 200 may be performed by another device. For the sake ofexample, steps of the method 200 are described as being performed by aprocessor.

The method 200 begins in step 202. In step 204, the processor maymonitor delivery of an item of multimedia content to a first userendpoint device in a first stream of data (e.g., as a unicastcommunication). The item of multimedia content may comprise, forexample, video content (e.g., a television show or a movie) or audiocontent (e.g., music or a podcast). The item of multimedia content maybe delivered by a server to the first user endpoint device, where theserver may be operated by a content streaming service provider. Asdiscussed above, the first stream of data may comprise a plurality ofpackets that are sent to the first user endpoint device in a continuousmanner, where each packet of the plurality of packets contains a portionof the item of multimedia content.

In step 206, the processor may monitor delivery of the item ofmultimedia content (i.e., the same item of multimedia content beingdelivered in step 204) to a second user endpoint device in a secondstream of data (e.g., as a unicast communication). The item ofmultimedia content may be delivered to the first user endpoint device bythe same server that is delivering the item of multimedia content to thefirst user endpoint device, or by a different server operated by thesame content streaming service provider. As discussed above, the secondstream of data may comprise a plurality of packets that are sent to thesecond user endpoint device in a continuous manner, where each packet ofthe plurality of packets contains a portion of the item of multimediacontent.

In one example, prior to steps 204 and 206, the processor may beinformed by the server(s) delivering the item of multimedia content thatthe item of multimedia content is being delivered. In one example, theserver(s) may notify the processor directly. In another example, theprocessor may monitor a buffer (e.g., a relay buffer) to which serversupload items of multimedia content that are currently being streamed, asdiscussed in further detail below.

In steps 204 and 206, the monitoring may involve collecting data thatidentifies the respective progress each of the first user endpointdevice and the second user endpoint device has made with respect toplayback the item of multimedia content. For example, if the item ofmultimedia content comprises video or audio content, the first userendpoint device and the second user endpoint device may each send aframe identifier that indicates a particular frame of the item ofmultimedia content and a timestamp indicating a time at which first userendpoint device or the second user endpoint device played the particularframe. The data may further include information such as the remainingcapacity in the respective buffers of the first user endpoint device andthe second user endpoint device (e.g., number of bytes, percentage ofoverall capacity, etc.), which portions (e.g., packets or chunks) of theitem of multimedia content are currently contained in the respectivebuffers of the first user endpoint device and the second user endpointdevice, current respective locations of the first user endpoint deviceand the second user endpoint device if either device is mobile (e.g.,global positioning system coordinates), confirmation that respectiveusers of the first user endpoint device and the second user endpointdevice are currently playing the item of multimedia content, and otherdata.

The data may be sent by the first user endpoint device and the seconduser endpoint device in response to a request issued by the processor.For instance, if the processor is aware that the same item of multimediacontent is being delivered to the first user endpoint device and thesecond user endpoint device, the processor may identify this as apossible opportunity for consolidation of data streams. Alternatively,the first user endpoint device and the second user endpoint device maysend this data periodically, randomly, or in response to the occurrenceof a predefined event. For instance, if a user of the first userendpoint device detects a change in the quality of the item ofmultimedia content (e.g., a change in the image resolution of a video),the first user may trigger sending of the data to the processor in orderto troubleshoot the change in quality. The change in the quality of theitem of multimedia content may indicate a change in network conditions(e.g., a reduction in bandwidth, an increase in latency, etc.). Thechange in quality could also be automatically detected by the first userendpoint device.

In step 208, the processor may determine a difference in playbackbetween the first stream of data and the second stream of data, based onthe monitoring performed in steps 204 and 206. For instance, theprocessor may determine how much time or how many frames exist betweenthe portion of the first stream of data that is currently being playedand the portion of the second stream of data that is currently beingplayed.

In step 210, the processor may consolidate the first stream of data andthe second stream of data into a third (single) stream of data, bysending an instruction (e.g., to the server(s) delivering the firststream of data and/or the second stream of data) to modify the speed ofat least one of the first stream of data and the second stream of data.In one example, modifying the speed of a stream of data may involvemodifying the speed with which the stream of data is played. Forinstance, if the first stream of data is determined in step 210 to befifteen seconds ahead of the second stream of data, then playback of thefirst stream of data may be temporarily slowed while playback of thesecond stream of data is temporarily sped up until the first stream ofdata and the second stream of data match (e.g., are playing the sameframe at the same time). In one example, slow down or speed up ofplayback may adjust the playback speed by less than twenty percent ofthe current speed. In another example, slow down or speed up of playbackmay adjust the playback speed by between one and ten percent of thecurrent speed to avoid noticeable alteration of the item of multimediacontent. Moreover, in one example, the processor may only attempt toconsolidate the first stream of data and the second stream of data ifthe difference between the streams does not exceed some thresholddifference. The threshold difference may vary depending on the length ofthe item of multimedia content (e.g., the threshold difference may beeleven percent when the item of multimedia content is forty-five minuteslong, but may be smaller when the item of multimedia content isshorter).

In another example, modifying the speed of a stream of data may involveinserting additional content, such as advertising content, episoderecaps, news clips, or the like into the stream of data. For instance,if the first stream of data is determined in step 210 to be fifteenseconds ahead of the second stream of data, then a thirty-secondcommercial may be inserted into the first stream of data while a fifteensecond commercial is inserted into the second set of data. The timingand durations of the commercial playbacks may be determined in each datastream so that by the time the respective commercials end, the firststream of data and the second stream of data match. Thus, streams ofdata may be consolidated by inserting commercials or other content ofvarying lengths. In one example, the commercials (or other content) maybe inserted into predefined segments of the item of multimedia content(e.g., scene cuts, fades, etc.) or may be inserted when a user pausesplayback.

Consolidating the first stream of data and the second stream of data mayinvolve identifying the codec(s) used to compress the item of multimediacontent in the first stream of data and the second stream of data. Forinstance, different video playback protocols may use differentcompression schemes. If necessary, the item of multimedia content may berecompressed according to a new codec to facilitate consolidation. As aresult, the third stream of data may employ a new video playbackprotocol (i.e., a video playback protocol not employed by the firststream of data or the second stream of data). Depending on the source ofthe item of multimedia content (e.g., whether the controller has theability to alter the actual content), the new video playback protocolmay be implemented in the actual video playback or may be implemented asan envelope to the original video playback protocol (i.e., the protocolemployed by the first and second streams of data).

In step 212, the processor may send instructions to cease delivering thefirst stream of data and the second stream of data and begin deliveringthe third stream of data to both the first user endpoint device and thesecond user endpoint device. Thus, bandwidth consumption may be reducedby delivering a single stream of data to the first user endpoint deviceand the second user endpoint device in place of separate streams ofdata. At this point, delivery of the item of multimedia content maybecome a broadcast communication (rather than two separate unicastcommunications).

The method 200 may end in step 214.

As discussed above, some examples of the present disclosure may insertstrategically chosen advertising content in order to enableconsolidation of streams of data. In some examples where it is desirableto conserve bandwidth, presentation of advertising content may besacrificed (e.g., shorter commercials may be shown) in order to achievea reduction in bandwidth consumption. In other examples where bandwidthconservation is not a priority, advertising content could be presentedin a manner that maximizes revenue (e.g., longer or a greater number ofcommercials may be shown).

In one example, consolidation of the first stream of data and the secondstream of data may be facilitated by the use of a relay buffer, such asthe buffer(s) 180 of FIG. 1. In this case, the relay buffer may comprisedownstream temporary storage that is not attached to or part of aspecific user endpoint device. The controller may instruct each serverthat is streaming to a user endpoint device to upload content beingstreamed to the relay buffer within some threshold period of thestreaming starting. The content held in the buffer could then be used tosatisfy subsequent requests for the items of multimedia content that arealready being streamed. Content held in the relay buffer may be deletedafter a predefined period of time.

Furthermore, as discussed above, some examples of the disclosure mayfurther conserve bandwidth by uploading items of multimedia content toservers in a strategic but temporary manner. For instance, if arelatively large number of users in the same location (e.g., within athreshold distance from each other) is expected to stream the same itemof multimedia content at roughly the same time, the item of multimediacontent could be uploaded to local servers in that location for apredefined period of time. This may then avoid the need for the users tostream the content over a potentially large distance. The item ofmultimedia content could be deleted from the local servers at or after apredefined time (e.g., x hours after upload) or upon a requests for theitem of multimedia content falling below a predefined threshold (e.g.,no more than y requests over x hours).

As an example, a large number of users on the West Coast of the UnitedStates may be expected to view the same episode of a television showcurrently being viewed by viewers on the East Coast, just three hourslater. The television show could be dynamically uploaded to servers onthe West Coast prior to the West Coast users requesting the show. Asanother example, cultural norms may drive the selection of content thatis temporarily stored on local servers. For instance, moreholiday-themed content could be stored during the month of December.

Moreover, although not expressly specified above, one or more steps ofthe method 200 may include a storing, displaying and/or outputting stepas required for a particular application. In other words, any data,records, fields, and/or intermediate results discussed in the method canbe stored, displayed and/or outputted to another device as required fora particular application. Furthermore, operations, steps, or blocks inFIG. 2 that recite a determining operation or involve a decision do notnecessarily require that both branches of the determining operation bepracticed. In other words, one of the branches of the determiningoperation can be deemed as an optional step. Furthermore, operations,steps, or blocks of the above described method(s) can be combined,separated, and/or performed in a different order from that describedabove, without departing from the examples of the present disclosure.For instance, some steps of the method 200 could be performedsimultaneously. As an example, step 204 could be performedsimultaneously with one or more of steps 206 and 208.
